In summary, it's super unprofessional. Shopee's HR didn't reach out to me to schedule the time for the phone interview until nearly 2 months after I submitted my resume. At the time arranged for the phone interview, I waited for more than 30 mins for the call but there was no one calling me. I emailed the HR and he said that the previous meeting was postponed, which resulted in the delay of our interview. (And sure, he had no time to notify that to me by email :) We arranged another time for the phone interview and it went really well (at least I felt). But there was no update from the Shopee for the following 2 weeks. I emailed them to see if there is any update, and I got a reject letter the day after I sent the email.
